Volcanic rock is difficult to crush due to its high hardness (Mohs hardness), high silicon content and easy to wear the equipment when crushing, traditional crushing equipment is easy to wear and low efficiency. With its unique design and technical advantages, Roll Crusher becomes the ideal choice for processing volcanic rock.

Volcanic Rock Crusher
1. Roll Crusher High Efficiency Crushing and Particle Size Control
Squeeze and Shear Dual Action
Double rolls rotate relative to each other to generate high pressure squeeze and shear force. Which can quickly crush large volcanic rock and avoid clogging problem.
Precise particle size adjustment
Hydraulic system adjusts the roll spacing (usually 1-5mm adjustable), the discharged particle size is uniform. To meet the fine demand of construction aggregate or mechanism sand.
Deep V-shape crushing chamber design
Dead zone-free structure improves the material passing rate and adapts to the high hardness characteristics of volcanic rock.

Volcanic Rock Roller Press
2. Volcanic rock crushing abrasion resistance and durability
High wear-resistant materials
The rolls are made of high manganese alloy or thickened manganese steel (e.g. 20cm thick), which improves the wear-resistant life by more than 3 times and reduces the frequency of replacement (3 years free replacement for some models).
Overload protection mechanism
Spring or hydraulic overload protection device automatically backs off in case of hard objects to prevent equipment damage.
3. Energy saving and low maintenance
Energy consumption and noise control
High-efficiency transmission system reduces energy consumption by more than 30%, and the operating noise is lower than the industry standard, reducing environmental pollution.
Dust suppression
Closed structure with dust removal design, the amount of operating dust is low, in line with environmental requirements.
Convenient maintenance
Modular design, quick change of roller skins, automated lubrication, daily maintenance by only one person.
4. Economic benefits and applicability
Comprehensive Cost Advantage
The initial investment is moderate (tens to hundreds of thousands of yuan), but the running cost is low (less electricity consumption, low maintenance fee), and the long-term return rate is high.
Wide adaptability
can process dry/wet volcanic rock (with scraper anti-sticking rollers), adaptable to fixed production line or mobile station, with hourly output covering 4-400 tonnes.
Enhanced quality of finished products
Low overcrushing rate and rounded grain shape (‘stone hitting stone’ mode), enhancing the added value of mechanism sand.
The roller crusher is based on the core of ‘high pressure crushing + wear-resistant and durable + intelligent control ’, which is perfectly adapted to the high hardness characteristics of volcanic rock. Its high efficiency and energy saving, easy maintenance features, especially suitable for gravel plants, mines and other medium and large-scale production scenarios (recommended models such as Huasheng Ming 1500 * 1000 type, 200 tonnes per hour). Priority is given to models with thicker roller skins and hydraulic systems (such as the knife shark manganese steel alloy rollers), and optimise the yield rate with the screening closed loop.
